To aZZ whom it concern}: i l

1' Be it known'that cI-Q EDWARD LAHAN, a citizen of the Unitedx States, re

siding atiQuincy, in the county of'A dams ing is azspecification 'lhe present lnv'entjion appertainsj gggenerg and State ioff Illinois; have invented; a. new and useful Sp1'ing'-Hub, ofwhich;the;f l

ally to vehicle wheels, and relates more particularlyi to a novel and improvedresi-lient or. spring hub forwautomobile and other vehicl'e wheels. 1

It isfthe primary, objectofthe present inventioh to provide a lhub of, peculiar and unique construction, which shall be operable I to permit the vehicl.e *wheel a)- .yield; verti- 1 cally,-in' orderthat the wheel may have vertical relief when traversing a rough surface.

Another object of the present invention is to provide a device of the nature indicated embodying a novel assemblage of 1 parts, in order thatthe present device fwill'have superior'advantages over existing. devices of this 'characten'and in order to best adapt the present'device forthe purposes intended With the foregoing and other objects in view which will'appear as the description 5 that changesin the precise; embodiment of a the invention hereln disclosed," can bemade withinlthe scope of what is claimed, without proceeds, the invention resides in'the combination' and arrangement. of parts and. in the details-"of construction hereinafter described andwcla-imed, it being understood departing from: the spirit of the-invention. Thepresentinventionhas been illustrated ,in its preferred en bodiment, in the accompanying drawing, wherein a sectional views taken on the lines 3 3 and Figure 1 is an outside face view of the improved hubr Fig, 2 isa"sin1ilar view with the face or cover plate removed to expose the interior mechanism. Figs. 3and' 4 are i -4C of Fig. 1 respectively.

In carrying out thepresent invention, ref- 1 erence being had in detail to the drawing, there is provided a circular disk or plate 1 of relatively large thickness, andhavinga squareor rectangular opening 2, the upper I and lower ends of the opening 2 being provided with steps or bearings 3 adjoining the corners, oftheopening In connection with the plate or body 1, there areemployed two circular disks or plates 4:,which are of larger 3 diameter than the member 1, and which rest against the opposite sides of the saidinem- I Specification areal-5' Patent. mac w filed aui za,

ber, the-innerlplate 4 forming back plate,

andthe outer plate 1, forming a cover or face plate closingthe opening 2. Thus, the

" member or body -1 togetherwith the plates 4: constitute ,a case for the purposes which will herelnafterappear. Theparts 1 and are detachably secured together in order; that they may be readily assembled and separated,=andtc this end, screws 5 are preferably passed'loosely through theface plate 4 and member 1, so astojthreadedly engage the back plate 1 to clasp the said parts tightly together. The peripheries or margins of the plates eextend beyond the peripheryof the meinbeiil and an annulus or ring 6 is mounted for ,rotation between the edges of the plates 1', over ,"thejmember 1,

suitable roller or anti-frictional bearings 8 being preferably dlsposed-between the annulus or ring '6 anddthe' m'ember 1 to perlnit 1 g Patented Sept. 22, 1914. ielams rialuo.789,596. I

- the annulus to rotate freely; To the annulus 6, the spokes 7 are sepured in any desirable manner, the detailsof which are of'no particular moment. ltis evident that the roller bearings 8 will be heldbetween the annulus Band the member 1 by the-plates 4:, the annulus also vbeingheld for rotation between the saidpl ates,,ini'order that when the face a plate is removed,- theannulus, as well as the roller bearings, maybe readily slipped off of the memberor body 1. f

.The axle of the wheel has been designated bythe numeral 9,"the same being provided Tit/113a spindle ,10 extending through verti cally elongated openings or slotsfll vprovided in the central portions of the plates imidway between and parallelfwith the'sides of the. opening2. Aa nut 12 threaded onto the .end of the spindle 10 to "engage the face plate ,4; for retainingthe hub in position on the spindle, it "beingevident' jthat the'slots or openings 11;perrnit the casing embodying themembers 1 and 4i4eto reciprocate or vibrate vertically; l

A bearingblock13embraces the spindle 10 within the member 1, and its upper and lower ends are provided 'with the notches or seats14, while the sides of the bearing block "13 are provided with the projections 15 having their ends snugly engaging the sides of the opening 2 for sliding movements.

Coiled wire compression springs '16'are dis:

posed between the projections. 15 and the respective steps or bearings 3, and between the seats 14 of thebearing block '13 and the ends of the opening intermediate the steps 3, the upper and lower sets of springs Working in opposition to each other, and tending to normally hold the bearing block 13 centrally of the hub structure.

Rectangular plates 17 are mounted on the spindle 10 over the inner and outer faces of the bearing block 13, the plates 17 having central openings through which the spindle passes. The projections 15 are greater'in width than the bearing block 13, so as to provide shoulders 18 engaging the side edges.

of the plates 17 which are disposed vertically, in order tomaintain the plates in their vertical positions. It will be observed that the plates 17 close the openings or slots 11, in order to exclude dusta-ndother extraneous matter the ends of the plates 17 being also adapted [to strike the ends of the opening 2 to limit the vertical movements of the vehicle wheel proper with respect to the spindle or axle. The bearing block 13 is so mounted upon the spindle 10, as to be constrained against rotation, whereby the memher 1 carrying the annulus 6, will be re strained for vertical reciprocatory movements against the tension of the respectivesprings 16. It may thus be said, that the bearing block is elongated and is disposed between and parallelwith the upper and lowerends of the opening 2, with the ends of theblock slidablyf engaging thesides of the said opening. The block is provided with a central spindle-receiving aperture cooperating with theslots 11 and the sides of the central portion of the block are spaced vehicle wheel, or rather the tire thereof, may

have vertical relief, to provide a cushioncopies of thispatent may be obtained for ing effect, or to absorb the shocks to which the wheel is subjected in use. Thus,'when the wheel is given an upward thrust, the

nember 1 willbe forced upwardly against the tension of the upper set of springs 16,

and after the upward thrust has been removed, the upper set of springs will recoil to freturnthe vehicle wheel to norm l Position against the tension of the lower; set of springs. 'The other advantages of the present device will be manifest frointhe foregoing, wit-hout" the necessity of a lengthy description, it being noted that the objects aimed ath'ave been carried out satisfactorily.
